Oh, I've had enough of that, too. My horse is nice, but he isn't fancy, extra fast or super agile, so I sometimes hear him being compared to horses of other breeds who have special talents in areas that he isn't even built for. I used to take it to my heart, but now I've learned to smile about such remarks - well, so what that your horse can trot faster than mine? He's a trotter, for goodness sake, of course he can trot faster! What's even the sense to compare anything! I love him all the same.
(I did have my comeback to the trotter's owner, though - we decided to go for a gallop not long ago, and of course the trotter couldn't keep up my drafties thunderous gallop.
